Characterization of Community-Scale Smokeless Biochar Production from Corncobs for Potential Soil Amendment and Climate-Smart Agriculture
A community-scale smokeless vertical kiln operating at 415–435 °C for 150–180 minutes yielded 23.3–28.3% corncob biochar. The product contained about 71% carbon, had a moderately alkaline pH and macroporous structure, and showed moderate stability indicators. Theoretical sequestration was estimated at 0.69–0.74 tCO2-eq per tonne of dry feedstock.
